Added my RefBot code, and the hunter_prey.* files that it needs. Brad's old code is still existing in main.c.old, and the Makefile for it is in Makefile.old. The new RefBot runs on a robot, not a USB XBee.

Fixed the #include so it can find the linefollow header. This should be fixed so it can find the .h file in the proper directory. Also added lineFollow.c and lineFollow.h to this directory so main can find them. They will not be updated when the real copies update.

Added beginning of wireless protocol for traffic navigation, and added code for handling intersections, with the exception of that code that involves navigating the intersection (so just the code that deals with wireless, the intersection queue (as I see it), and deciding when to go).
